pdistmex - Error - Undefined function 'pdistmex' for input arguments of type 'double'.

Hello,

I have got the following problem. The function pdist(X,dist) gives me the following error.

"Undefined function 'pdistmex' for input arguments of type 'double'."

I dont understand why it does not work, because X is always a 'double' or isnt it?

The following lines are the code from the MatLab function pdist(X,dist).

% Call a mex file to compute distances for the standard distance measures
% and full real double or single data.
if ~strcmp(dist,'usr') && (isfloat(X) && ~issparse(X)) % ~usr => ~complex
    additionalArg = cast(additionalArg,class(X));
    % Here is the error. 
    Y = pdistmex(X',dist,additionalArg)  
elseif ~strcmp(dist,'usr') && isfloat(X) % ~usr => ~complex
    additionalArg = cast(additionalArg,class(X));
    Y = pdistSparse(X', dist, additionalArg);

Hello,

You usually get this error if don’t have license to the required toolbox. Ensure that you have license to ‘Statistics and Machine Learning Toolbox’.

If you have a valid license and still you are getting the error then run the following commands

toolboxcache 
rehash toolboxcache
